BOLT-HOLDER.

SPECIFICATION forming part of Letters Patent No. 617,129, dated January 3, 1899.

Application filed March 3, 1898. Serial No. 672,457. (No model.) I

To all whom it may concern:

Be it known that I, DAVID L. SHUMATE, a citizen of the United States, residing at Excello, in the county of Macon and State of Missouri, have invented a new and useful Bolt- IIolder, of which the following is a specification.

My invention relates to devices for holding the heads of bolts to prevent the bolts from turning while the nut is being removed from it with a wrench, the invention being especially applicable to the removing of plowbolts, but capable of use in many other positions, such as removing the tire-bolts of wagons.

The object of my invention is to provide a simple, cheap, strong, and durable device reliable and eifective in operation.

With this object in view my invention consists in a bar of steel or other suitable metal provided with teeth or jaws at one end to engage upon the head of the bolt, a handle at the opposite end to facilitate the operation of the device, a series of notches formed in one edge of the bar, a spring secured to the bar and overhanging the notches, and a hooked piece bifurcated at its rear end and having a pin adapted to be dropped into either of the notches, as may be desired or necessary, the spring normally bearing upon the outside of the notched bar and serving to retain its pin in engagement with the notch in which it is placed.

In order to enable others skilled in the art to which my invention most nearly appertains to make and use the same, I will now proceed to describe its construction and operation, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a perspective view illustrating my invention as applied to a plowshare in position to hold a bolt. Fig. 2 is a view illustrating the notched bar and spring in side elevation and the bifurcated hooked bar in elevation, the device being applied to a bolthead. Fig. 3 is a detail perspective view of the bifurcated hooked bar. Fig. l is a detail perspective view of the forward end of the notched bar with the spring secured thereto.

Like letters of reference mark the same parts wherever they occur in the different figures of the drawings. Referring to the drawings by letters, A 1ndicates a bar of steel or other suitable material, formed at B into a handle of any suitable size and shape to facilitate the use of the instrument. The opposite or forward end C of the bar A is bifurcated or notched, as at D,

forming two teeth or jaws D,which are adapted to engage in the head of the bolt from which the nut is to be removed.

The main body of the bar A is extended vertically, the handle end being widened horizontally, as shown in the drawings, and in the upper end of the main body is formed a series of notches E, sloping slightly toward the forward end of the bar. Immediately in the rear of the series of notches E the inner end of a flat spring F is secured to the top of front end I and bifurcated at its rear end to form prongs J, between the outer ends of which is secured a pin K.

The construction of my invention will be readily understood from the foregoing description, and its operation maybe described as follows: Referringespecially to Fig. :2, it will be seen that the jaws or teeth D D of the bar A are engaged upon the head of a bolt L from which it is desired to remove the nut M, the bolt extending through two plates N and 0. With the teeth or jaws D D of the bar A thus in contact with the head of the bolt L the bar itself isbrought to a position in line with the length of the bolt, when the hook I on the outer end of the hooked bar 5 H is engaged over the edge of the plate N and the pin K, connecting its forked ends, slipped under the spring F and dropped into the proper notch E to retain the bar A in its position as near as possible.

pressure is applied upon the outer end B of the bar A, the hook resting over the edge of The notches are inclined in- 75 In this position the plate N, acting as a fulcrum, by means of which the teeth or jaws D D Will be forced against the head of the bolt L and Will hold it sufficiently against turning to permit the nut M to be removed with the wrench.

As before stated, my invention is intended to be applied especially for use in removing bolts from plows; but it will be readily understood that it may be used with equally good results in removing the tire-bolts from wagons and in removing bolts from all classes of machinery where it has heretofore been found difficult to hold the head against turning while removing the nut.

While I have illustrated and described the best means now known to me for carrying out my invention, I do not Wish to be understood as restricting myself to the exact details of construction shown and described, but hold that such slight changes or variations as might suggest themselves to the ordinary mechanic would properly fall within the limit and scope of my invention.

Having thus fully described my invention,

K, adaptedto be engaged in any one of the notches of the series, and the fiat spring, F, secured to the upper surface of the bar, A, in proximity to the outer end of the series of notches and lying normally in position over the upper edge of said bar A, to retain the pin, K, in engagement in one of the notches, all substantially as described.

DAVID L. SHUMATE.
